All the FESTOOL vacuums not only connect seamlessly with the tools but can also be used as a general shop vacuums for wet and dry applications. The tools in the kits take into account many situations from a standard workshop, to a general purpose vacuum (the universal) to sets for installers working on-site. All the sets except the Industrial come with Systainers that can be attached to the vacuums for easy storage and transport. The hoses that come with the sets are 1 7/16" diameter x 11.5’ long, except for the Industrial set, which has a 2" diameter x 8.25’ long hose. These hoses are all larger in diameter than the stock tool attachment hose, for better clearing of regular debris. The larger hoses can be used with the tool with a reducing attachment. The Compact set does not include a hose. The sets will fit all the CT model vacuums.
